Enhancing trust through digital Islamic finance and blockchain technology

Purpose This paper aims to provide a reflective discussion on the different avenues of blockchain application in Islamic finance in promoting trust and transparency for increased accountability between parties involved in the delivery of Shari?ah-compliant products and services. Design/methodology/approach This paper discusses on blockchain benefits in Islamic finance while providing an illustration with smart Sukuk. Having identified the advantages of the development of Islamic financial technology (i-FinTech), this study ends by debating a couple of challenges (computational codification of Shari?ah principles and environmental impact) that have to be addressed to promote the development of a real sustainable Islamic FinTech. Findings This paper also identifies two challenges in using blockchain in i-Fintech. The first challenge refers to the extent to which Shari?ah principles can be computationally encoded. Blockchain makes public all transactions that ease Shari?ah compliance checks and determine if these transactions are Islamic in nature but this check can be done only after their operation. The second challenge is related to the algorithmic protocol used to validate smart contracts (including smart Sukuk). This situation calls into question the principles of Maqasid al-Shari?ah according to which transactions should not harm society. Originality/value In the current debates related to the development of Islamic FinTech, this paper also identifies two challenges in using blockchain in i-Fintech.
